ABSTRACT:
In a texturing system with a texturing nozzle and a first drum connected thereto and a further drum, a thread is guided on the outlet side of a texturing nozzle at the circumference of a drum in the form of a strip by friction and at least in part in positive manner, so that the longitudinal speed of the strip at the circumference of the drum corresponds with the circumferential speed of the drum in the area of the guide, whereby, by means of a pressure difference in an air guidance system, the effect is achieved by pressing the strip onto the surface of the drum. Further, the thread is guided in relation to its conveying speed and packing density, by positive and friction guidance under the imposition of air, as far as an outlet point on the first drum, and is transferred onto a second drum, on which the strip is cooled, extended if appropriate, and passed on to further guide or conveying rollers, respectively.
